Hi Chris,
Tell me if I'm teaching you to suck eggs, but it's quite easy to get AVs in
your code by e.g. referring to an object that doesn't exist any more etc.
Even though the error message lists a Windows DLL (user32), this doesn't
mean that it's not a bit of your code causing the AV.
E.g., if you have two variables referring to the same object, and you
destroy the object using one of the variables, you would still be able to
call methods on the other variable, but you would be likely to get an AV,
'cos the memory that the object resided at has been reclaimed by the OS.
If it's not a problem with your code, it might be a bug in the component
you're using.
Again, I might have missed the point of your original email, but I hope this
helps...
Cheers,
Conor
